Problem/Motivation

If search backend dies, route entity.search_api_index.canonical will throw fatal error. This is because $index->status() assumes the backend is up-and-running.

Steps to reproduce

1. Create server and index.
2. Shut down search backend, e.g. sudo service elasticsearch stop
3. Go to /admin/config/search/search-api/index/{index_name}

Fatal error is produced.
